High pressure fluid pump |
摘要 |
A free piston compressor for gases and liquids in which the positive pressure of the incoming fluid holds the piston against the piston rod during the intake stroke. In a specific form, the cylinder head is a plug of larger diameter than the piston which can be unscrewed to permit removal and replacement of the piston for service.
